Medium-scale integration refers to an early generation of integrated circuits that packed tens to a few hundred transistors onto a single silicon chip. This level of integration allowed engineers to replace boards full of discrete transistors with single packages performing specific functions, like decoders, counters, and multiplexers. While the term is largely historic, it marks the transition phase before large-scale integration made microprocessors possible.
Those old 7400 series logic chips are classic MSI, handling basic counter functions without needing a full microcontroller.
